Repsis V1. A Fully enclosed CoreXY 3d printer with a heated chamber

thingiverse

This is a 3D printer I designed around the CoreXY design by Lehavier: https://www.thingiverse.com/thing:2138286 With a fully enclosed design and heated chamber, it works very well with four big blowers on the side for convection and as a layer fan. Apart from the 3D printed files, you will need all the hardware from the Lehavier design, replacing the MGN12H with MGN12C carts, using 250mm rails. You will need the following 2020 profiles (in mm): CoreXY: 2 x 330 2 x 306 Base: 2 x 330 2 x 266 Sides: 4 x 380 Twenty corner brackets are also required. Three motors for the XYZ and one motor for the extruder must be used. A Titan Aero hotend/extruder, a BLtouch, and this heater: https://www.aliexpress.com/item/AC-220V-500W-Electric-Ceramic-Thermostatic-PTC-Heating-Element-Heater-Surface-Insulation-Constant-Temperature-Air-Heating/32916798368.html are necessary. Four big blowers (https://www.aliexpress.com/item/5-pcs-lot-GDT-DC-2P-Big-Airflow-Cooling-Blower-Fan-97-97x33mm-9733-turbo-Cooler/2002250475.html) must be installed. 310 x 254 x 3 mm glass for the front door (glue the hinge and handle to the glass with epoxy), 236 x 254 x 2 mm glass for the sides, four neodymium magnets of 10mm diameter by 4mm thick for the handle are required. The panels are made of 4 mm thick alucobond, an aluminum polycarbonate composite milled with a CNC. It is pretty cheap and easy to work with. I uploaded a DXF to mill them. You will also need to make some 5 mm separators for the side panels. I included another DXF. The LCD is a MKS Mini 12864. If you want more insulation, use 5mm aluminized polyethylene foam on the inside like in the pictures. I'm also uploading a Marlin with the chamber on the LCD. For the Z-axis, you'll need: 4 x LM16UU 2 x 280 mm 16 mm smooth rod, 1 x 238 mm TR8x8 leadscrew, 1 x TR8x8 nut and 1 x 5 x 8 coupler. 1 x 608 ZZ bearing Below the hotbed is a 10mm cork plate for thermal insulation. I'm also uploading the Solidworks files.
